前不久,笔者有幸参加了全市青年教师教学大赛的评价工作,由于是考查青年教师的基本功,所以,抽签确定的参赛内容都是概念讲授课.从授课情况来看,相当一部分选手概念讲授要么浮光掠影,要么颠三倒四,要么避而不谈,总之,讲授是不清楚的,学生学习的效果自然非常差.我们知道,概念是数学的基石,一切公式、法则、推理等等(或者说数学学科理论体系)都是建立在数学概念基础之上的.因此,教师的概念教学尤为重要 Not long ago, I was fortunate enough to participate in the evaluation of the city’s youth teacher teaching contest, as is the basic skills of examining young teachers, therefore, the lottery to determine the content of the competition is the concept of lectures from the lectures point of view, a considerable part of the concept of player or supernatural , Either the top or the bottom, or avoid it, in short, the teaching is not clear, the effect of student learning naturally very poor.We know that the concept is the cornerstone of mathematics, all formulas, rules, reasoning, etc. (or mathematical theory system ) Are based on the concept of mathematics.Therefore, the concept of teaching teachers is particularly important
